Tom Anderson, one of the activists at the Instro protest, said: "We are here because we want to stop Elbit from supplying weapons which are used to massacre people in Gaza and Afghanistan.

"In 2013 I visited Gaza and spoke to the survivors of Israeli drone strikes. They told me that they wanted people to take action to prevent the companies that manufactured the drones that killed their loved ones from making equipment that will cause others to suffer the way they have."

Protester Lucy Marshall added: "Optical and camera systems like those manufactured at Instro Precision are supplied by Elbit for use on drones and also for camera systems on the apartheid wall.

"We are here to take action to prevent Israel from continuing its oppression and apartheid against the Palestinians."

A Kent police spokesperson said: "Kent Police is currently monitoring a reported protest taking place at the Pysons Road Industrial Estate in Broadstairs.

"As with all such events, the primary role of Kent Police is to facilitate peaceful protest, which is lawful, whilst also ensuring public safety and minimising any disruption. Resources will be deployed as necessary and appropriate."

IBTimes UK is awaiting comment from Instro.

Correction: The article previously stated London Palestine Action were involved the protests. This has since been amended.
